Description
Technical field
The present invention relates to casting fields, are intended to eliminate the low of aluminum vehicle wheel hump spot shrinkage defect more particularly to a kind of
Press casting mould.
Background technology
In the production of aluminum vehicle wheel low pressure casting, the hump of inner rim position(A-quadrant in Fig. 1)Structure is thick big, forms
Apparent thermal center is the relatively conventional position of casting flaw.Hump is in the distal end for filling type, and so far temperature has dropped for molten aluminum flowing
It is much lower, shrinkage defect can occur due to front end feeding capacity deficiency;The position casting structure is more thick big, and positioned at inner rim
Among wheel rim, effective cooling often can not be directly arranged on mold, causes the aggregation of heat, molten aluminum setting rate is slow,
Cast-internal coarse grains, mechanical property are low.In actual production, because hump position casting it is unqualified caused by waste product account for compared with
Big ratio, all serious forming quality for affecting wheel, reduces to the success rate of client's sample presentation.
Invention content
Present invention aims to solve the deficiencies of the prior art, and provides a kind of a kind of low pressure cast aluminum wheel die improved,
The structure has effectively eliminated hump thermal center, the shrinkage defect for solving cast-internal by strengthening Local cooling;Crystalline substance is refined

A kind of improved low-pressure casting die of aluminum vehicle wheel, including bed die, sprue cup, sprue bush, filter screen, spreader, side
Mould, backform, cooling pipe;Wherein backform, bed die, side mould together constitute the cavity of mold, ensure that the smooth of wheel casting
Forming.
For hump position, V-groove is set in the model Cavity surface of side, is designed with the shape with hump profile, on length direction
Including entire thermal center region;Ditch groove depth 1-1.5mm, 60-120 ° of angle, on side, the circumferentially spaced about 10mm of mould is evenly distributed with.
The back of the body intracavitary of mould on side, the position setting cavity of corresponding hump, with wheel casting concentric design, structure annular in shape;
The bottom surface of cavity is designed with the shape with hump profile, is 8-12mm away from cavity surface wall thickness value;The height dimension of cavity and hump thermal center
Range is suitable;The two sides of cavity are left to the safe wall thickness of few 10mm far from side mould mating surface, to ensure the use intensity of mold.
Stainless steel tube is selected to make cooling pipe, including main air hose and annular branch two large divisions;Main air hose perpendicular to
Annular branch, and it is designed as single air inlet form;Annular branch and wheel casting concentric design, air hose are 5- apart from cavity bottom surface
10mm;Annular branch both ends need to carry out welding closure, to form the pipeline of closing;Wind aperture is processed on annular branch road, it is small
Hole is axially perpendicular to cavity bottom surface;Outlet air hole diameter is designed as 3mm, and spacing 10-15mm is evenly distributed on circumferencial direction;Cooling is opened
When, compressed air acts on die surface by outlet air aperture, and quickly takes away the heat of aggregation, so as to fulfill the cooling of casting
Solidification.
The cooling pipe made is installed in the cavity of side mould, is fixed with welding or bolted mode,
To ensure work well.When filling type and starting 20-30s, the cooling of hump position is opened, closes, flows after inner rim completely solidification
General control is measured in 40-80m3/ h moves in circles by this technological parameter, you can realizes that hump thermal center position is flawless continuous steady
Fixed production.
The configuration of the present invention is simple, it is easy to accomplish:For hump position, groove is designed in the model Cavity surface of side, increases mould
The heat dissipation area of tool improves the natural cooling ability of mold;On side, mould back of the body chamber processes cooling cavities and is mounted with cooling tube
Road has carried out thermal center to concentrate cooling, has realized the quick export of heat, improve the setting rate of molten aluminum, ensure that effectively
Feeding, the defects of preferably resolving shrinkage porosite, the coarse grains that casting easily occurs;The synthesis mechanical property of product is improved simultaneously
Can, there has also been significantly improve for the safety index of wheel.

Specific embodiment
A kind of improved low-pressure casting die of aluminum vehicle wheel, including bed die 1, sprue cup 2, sprue bush 3, filter screen 4, spreader
5th, backform 6, side mould 7, cooling pipe 8;Wherein, bed die 1, backform 6, side mould 7 together constitute the cavity of mold, ensure that wheel
The smooth forming of casting.
Aluminum vehicle wheel low pressure casting belongs to bottom centre's cast, and sprue cup 2, sprue bush 3 and filter screen 4 constitute main pour
Injection system, and in the centre bore of bed die 1, when high temperature molten aluminum enters cavity, put down under the shunting guiding role of spreader 5
Surely, uniformly, smoothly fill type, to ensure the subsequently good solidification and crystallization process of casting.
For hump A positions, V-groove 72 is processed in the cavity surface of side mould 7, is designed with the shape with hump profile, it is long
It spends and includes entire thermal center region on direction;72 depth 1-1.5mm of groove, 60-120 ° of angle, on side, the circumferentially spaced about 10mm of mould is equal
Cloth;To ensure to make precision, avoid the occurrence of viscous aluminium problem, groove needs to select lathe number Milling Machining.
The back of the body intracavitary of mould 7 on side, the position of corresponding hump process cavity 71, and wheel casting concentric design, annularly
